To all whom t may concern.' l

Be it known that l, Or'ro J. Eisnnn, a citlzen of the United States, residing at New York, in the county and State of New York, have invented certain new and useful Improvements in Vehicleflires, of which the following is a full, clear, and exact specilication. v

This invention relates to vehicle tires, and has for its object to provide an improved resilient tire using compressed air `as the cushioning medium but which is not subject to puncture or other objections commonly found in ordinary pneumatic tires.

The invention will be first hereinafter described in connection with the accompany ing drawings, which constitute part of this specification, and then more specifically defined in the claims at the end of the description.

ln the accompanying drawings, whereinV Fig. 4 is a detailed plan view of oneof the sliding members arranged between the air reservoirs and the inner rim.

Fig. 5 is a section view of a portion of the tire on a larger scale to illustrate the hinged arms and compression cylinder more clearly, and

Fig. 6 is an under plan view of said arms, as they appear in Fig. 5, with the air reservoirs removed.

In Figs. 1, 2 and -3 of the drawings, 1 designates the hub of an ordinary vehiclewheel having spokes 2 andfelly 3. Around said felly is suitably secured a rim 4 hereinafter referred to as the inner rim. Spaced from said inner rim is an outer rim 5 which may constitute the tread of the tire. rlhe rims 4 and 5 are provided with flangesl 6 and 7, respectively, extending toward each other at the edges of the rims, and in the space partially housed between said rims by said flanges the cushioning means are mounted.l

Said cushioning means consists of a plurality. of air reservoirs 9 carried by the inner, rim and spacedV apart entirely around the tire, and aircompressing means extending between the inner and outer rims and arranged between adjacent reservoirs. The reservoirs 9 are preferably arcuate in form, as shownrin the drawings, so as to conform to the curvature of the tire vand felly of the wheel. Each reservoir is attached to the inner rim 4 by a block 10, which may be soldered', brazed or otherwise secured to the inner face of the reservoir, andy a screw or boltv 11 which passes outwardly through the inner rim andengages said block, which also serves to support the reservoir spaced away from the inner rim.

.lhe air compressing means comprises pairs of foldable arms 16 normally arranged at an acute angle to each other and extending between the inner and outer rims in the Spaces between adjacent reservoirs 9. `The outer ends of (each pair of arms 16 are: hinged together by a pintle 17, as best shown in Figs. 5 and 6, and said pintle also carries a roller 18 having antifriction engagement with the outer rim. The inner ends of said arms 16k are formed with rounded or cylindrical surfaces 15 to fit as knuckle joints'in grooves 14 in sliding members or plates 12 one of which is arranged between each of the reservoirs and the inner rim. VEach member 12 is arcuate in form to it the inner rim on which it is adapted to slide, and each of said members 12 is provided with a slbt 13 to loosely fit around the block 10, the slot being longer than the block toy permit the slidingmovement of said member. Y

Each of the arms 16 is formed with a slot 24 through which hose pipes 23 extend for coupling up the reservoirs 9 with thecompression cylinders 21 one of which-is arranged between each pair of arms. The arms 16 also have lugs 19 projecting inwardly intermediate of their ends, and vto said lugs there are pivoted piston rods 20 which extend loosely Athrough the ends of the cylinders 21, as best shown in F ig. 6, so as to contact with piston heads or disks 22 in the ends of the cylinders. The hose pipes 23 communicate with each cylinder near the center of the latter, that is intermediate of its ends, so that the piston heads may move inwardly toward the center of the cylinder during the compression of the air therein ibs without cutting off communication with said pipes.

Before the tire is subjected to a load the several pairs of oldablearms arranged at intervals around the same are held in sub-r stantially the same relative positions, as illustrated in Figs. l and 3, by compressed air which is torced into the reservoirs and cylinders through an ordinary lling not'.- zle or valve tubeV 25 communicating with one ot the reservoirs. rlhe air pressure in said reservoirs and cylinders may be about one hundred pounds when in use, and this pressure' will be equalall around the tire prior to its being subjected to a load. When a load is-placed onV the tire, however, the lower .portion of the outer rim, which is in contact with the road will be forced upward, as shown in Fig. 2, causing the pairs ot arms 1G below the horizontal center ot' the wheel to be spread apart and the arms above said horizontal center to be pushed closer together, due to the sliding movement oi the membersl l2 connecting said arms. The result is that the pressure of air inthe cylinders 2l below the horizontal center ot the wheel is reduced by the withdrawal or outward movement of the piston rods 20 as the arms are spread apart, while the pressure in the 'cylinders above the horizontal center is increased by the inward movement ot the piston rods and heads 22 as the arms are pushed toward each other. The difference in pressure at the bottom and top of the wheel will soon be vequalized it the wheel remains stationary, but when it is running or revolving the constant changing ot the pressure in the several cylinders will produce a superior cushioning or pneumatic effect which will insure comfortable riding.

The outer rim is preferably made ot steel or other material which is not subject to puncture, as are also the reservoirs 9, The flanges. 6 and 7 on the ims may be loosely connected together at intervals around the tire by links 8 which do not interfere with the displacement ot the outer rim under running conditions but prevent said outer rim trom simply revolving around on the rollers 1S which `would destroy the traction ot the tire. v

The annular spaces between the flanges 6 and 7 at the sides ont the tire may also be covered by strips 25 of rubber or other suitable elastic. material which ywill exclude dust and dirt but not interfere with the displacement of the outer rim as already explained. Said strips 25 may be secured to the tlanges by bolts 2G or other suitable fastening. means.

The cylinders 21 are preferably lined, as best shown in Fig. 5, with rubber bags 27 which are connected to the hose pipes 23 and through which the air passes from one reservoir 9 to the next. These. bags cannot be inflated su'liiciently to causethem to break on account of the restricting walls of the cylinders and the loose piston heads, the latter acting to compress said bags in the cylinders at the upper portion of the wheel when the tire is under a load as previously explained.
